Can You Really Use A Paint Sprayer As A Pressure Washer?

Have you ever found yourself asking, “Can you use a paint sprayer as a pressure washer?” Pressure washers are convenient because they produce a fast flow of water, allowing you to clean different surfaces at a much quicker pace.

But what if you don’t have one? Is it possible to use your paint sprayer? It’s a good question to ask. Be sure to check out this guide to find out if it would work! 

Using Paint Sprayer For Washing

Believe it or not, you can use a paint sprayer as a pressure washer. Because it's your equipment, you have the option of deciding how you're going to use it. However, there are some things you need to know beforehand.

1. Pressure Washers Are Faster

While paint sprayers and pressure washers are similar because they disperse liquid at a fast rate of speed, there are some differences between the two. 

2. It Can Be Messier With a Paint Sprayer

The paint sprayer tends to get a bit messier while producing more liquid, but this isn’t much of an issue if you’re trying to power wash a large area and want to get the job done quickly and efficiently.

3. Soap and Water Are Safe For the Paint Sprayer

It’s absolutely safe to put water or soap in a paint sprayer because these are two of the things that you’d need to put in your paint sprayer when cleaning it out after using it with paint anyway. So, if you decide to add both water and soap and use it as a pressure washer, it’s not a big deal. 

4. You Can Choose Different Power Options

You can choose the type of spray gun that you want to work with for pressure washing, such as a high-volume option with lower pressure.

When using a traditional pressure washer, you can choose from different nozzles that produce water at different degrees to clean various surfaces, such as 15 degree, 20 degree, and even 45-degree angles [1]. 

5. Choose the Right Paint Sprayer

If you plan to use your paint sprayer as a pressure washer, look for something with lower pressure when cleaning fragile items and higher pressure when working with tougher materials, such as concrete.

Can You Use A Pressure Washer As A Paint Sprayer?

While you can use a paint sprayer as a pressure washer, it’s not in your best interest to use a pressure washer as a paint sprayer. Although you can put paint in your pressure washer and use it to cover surfaces, it’s super messy.  

However, you can use a pressure washer in preparation for using a paint sprayer. Before painting, you want to make sure you remove any dirt and dust from the surface of what you are painting before adding a primer or a coat of paint. 

You can use your pressure washer to clean surfaces such as: 

  • Wood 
  • Metal 
  • Concrete 
  • Decks and Patios 
  • Entryways 
  • Walls  
  • Siding 
  • Gutters 
  • Windows  
  • Fencing 
  • Roofs 
  • Cars 
  • And more… 

If you don’t want to deal with a huge mess, it’s best to use a paint sprayer when you’re trying to cover different surfaces with a coating of paint, but use your pressure washer to clean the surfaces, first.
